HD Install :: CFdisk is going off the screen

oh awesome. so i did the boot from cd thing to the gui, opened bash, and instead of typing in cfdisk first I typed sudo su, enter, then cfdisk. it actually opened. yeah I have no idea what sudo su is. or X. I've never felt like such a noob before. I've dealt with dozens of win installs but this is all like "uh duh?" for me.

i'm finally getting around to searching for guides on this site. this one looks like it'll help me i hope. http://damnsmalllinux.org/wiki/index.php/Installing_to_the_Hard_Disk

X is sort of a nickname for the video server. There are several different ones, and many, many types of desktops so we just lump them all together and call them X when you are talking about using a graphical user interface. The commands sudo and su put you in super-user or administrator mode as long as the terminal is open. You need to be in that mode to do anything that can cause major damage to your operating system, so be careful with it.
